1.4 Programming the TPS26744E-Q1

Use either the TPS26742EQ1EVM or the TPS26744EQ1EVM (both orderable from ti.com) with a USB connection to a personal computer and three jumpers to the J10 connector on the PMP23501 board as shown in Figure 1-1. Both the PMP23501 and the above mentioned EVMs have male pins to make these three jumper connections easier. During programming, the PMP23501 needs 24V (or up to 60V) applied to the main input J1. The 3.3V from the PC USB connection powers the interface circuitry of the above mentioned EVMs.
